WILLIAM S. SUTHERLAND, OF OOOMBS WOOD, HALESOWEN, ENGLAND.

IMPROVEMENT IN PROCESSES FOR THE PRODUCTION OF CARBONlC-OXIDE GAS FOR HEATING AND WELDING- Specification forming part of Letters Patent No. 194,601, dated August 21, 1877; application filed March 12, 1877.

To all whom it may concern Be it known that I, WILLIAM SEDnoN SUTHERLAND, of Coombs Wood, Halesowen,

.in the county of Worcester, England, engineer, have invented a new and useful Process for the Production of Carbonic-Oxide Gas for Heating and Welding Purposes, which process is fully set forth in the following specification.

This invention has for its object to convert carbonaceous fuel into carbonic oxide with as littleexpenditure of heat as possible, when the said fuel is burned with a supply of air insufiicient to produce carbonic acid, and consists in causing the air to support combustion to travel upward around the outside of the producer, thence downward near the inside surface of the producer, and, finally, into the producer, beneath the fuel, where combustion takes place. The products of the said combustion pass in an upward direction through unburned fuel, thence in a downward direction round the outside of the producer to the main or any desired point for use.

In the manufacture of carbonic oxide, the

process herein described, consisting in heating the incoming air by the outgoing products of combustion, whereby radiation. and loss of heat from the producer are prevented, and the fuel is burned with a supply of air insufiicient to produce carbonic acid, substantially as specified.

WILLIAM SEDDON SUTHERLAND.
